By carefully maintaining the oil level and changing the oil at regular
intervals, the primary chain will be kept in excellent condition and will run for a
long mileage without attention. If the oil is allowed t o become dirty and partially
broken down, wear will develop on the primary chain, which will require constant
adjustment. (See Oil Chart. page 202).
